用混溶蒸发法制备出高聚物（ＰＥＯ）＿ｎ－ＣｕＢｒ＿２（ｎ＝４，８，１２，１６，２４）薄膜。并详细测量它们在０．１３５０ＭＰａ静水压范围的复阻抗谱，以及在０．１－２４００ＭＰａ静水压范围的交流电导率。结果表明：离子电导率与压力的依赖关系可分解为四段相迭加的线性关系。根据Ｘ射线衍射物相分析，它们分别归于ＰＥＯ非晶相的压力效应，ＰＥＯ结晶相的压力效应和析出新相ＣｕＢｒ＿２的压力效应。最后给出克服办法——添加少量增塑剂碳酸乙烯酯可增加（ＰＥＯ）＿ｎ－ＣｕＢｒ＿２薄膜的弹性，使压力下的离子电导率提高一至两个数量级。
Poly (ethylene oxide) _n-CuBr_2 (n = 4,8,12,16,24) thin films were prepared by the miscible evaporation method. Their complex impedance spectra in the range of 0.1-350 MPa hydrostatic pressure and AC conductivities in the range of 0.1-2400 MPa hydrostatic pressure were measured in detail. The results show that the dependence of ionic conductivity and pressure can be decomposed into a linear relationship between the four phases. According to X-ray diffraction phase analysis, they are respectively attributed to the pressure effect of PEO amorphous phase, the pressure effect of PEO crystal phase and the pressure effect of precipitating new phase CuBr_2. Finally, a solution is given - adding a small amount of plasticizer ethylene carbonate increases the elasticity of the (PEO) _n-CuBr_2 film and increases the ionic conductivity under pressure by one or two orders of magnitude.
